In this video from 2003, Louie Simmons, Chuck Vogelpohl, and Dave Tate perform rack lockouts. This exercise is used to improve glute, hip, and trunk strength. The goal is to improve the ability to extend the hips and lock out heavy deadlifts. This exercise is most commonly used as an accessory exercise and should not be confused with pin three rack pulls, which are commonly used as a max effort lower main exercise.
